Wednesday is the deadline for any homeowners with Knauf Plasterboard Tianjin Co. brand drywall join a class action against the manufacturer in the federal court.

Last month, KPT announced that it would give homeowners a one-time shot to file suit against it without having to pay the $15,000 that would be required to file suit through the normal procedures for international litigation in the Hague. Homeowners must provide evidence that they have KPT-brand drywall in their homes by Dec. 2.

Details on how to file can be found on Judge Eldon Fallon's web site for the consolidated litigation in U.S. District Court in New Orleans at http://www.laed.uscourts.gov/Drywall/Orders/PTO17.pdf
